SPECIFICATION forming part of Letters Patent No. 343,485, dated June 8, 1886. Application filed January 28, 1886. Serial No. 190,014. (No model.)

f? all whom at may concern.-

Be it known that I, Josnrn F. NooNn, of Peterborough, in the county of Hillsborough, State of New Hampshire, have invented a certam new and useful Improvement in Trusses, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which sald invention appertains to make and use the same, reference being had to the accompanylng drawings, formi'ng a part of this specificatlon, in which Figure 1 is a front elevation of a truss-pad embodying my improvement Fig. 2, a side elevation of the same; Fig. 3, a plan View of the plate detached, and Fig. at a vertical transverse section of the pad shown in Fig. 2.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates more especially to means for adjusting and securing the pad on the body ofthetruss; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effective device for this purpose is produced than is now in ordinary use. The nature of the improvementwill be read- 1ly understood by all conversant with such matters from the following explanation.

In. the drawings, A represents the body of the truss or the rod by which the pad is secured to the spring; B, the face-plate; O G, the clamping-plates; D, aplate which I denominate the cover, and E the nut. A rectangular chamber, H,is formed beneath the plate B, in which the nut E is disposed. An elongated slot, m, opens through the plate B into the chamber H, as bestseen in Fig. 3. The nutE is considerably smaller in diameter laterally than the width of the chamber H and slightly thinner than the depth of said chamber, thus enabling it to be moved about freely'therein; but it is sufficiently large to prevent it from being withdrawn through the slot or opening m when so moved. The clamping plates (J G are provided with corresponding grooves in their adjoining faces for receivingjthe body A and said plates, and the cover D provided with corresponding registering holes, through which two set-screws, w 00, are passed into holes 12 o in the nut E, the holes in the clampingplates and cover through which the screws pass being unthreaded and those in the nut threaded. The plate B is provided with apad, J, which may be of ordinary form and construction, and which is secured thereto by the screws 2 in the usual manner. The coverD is sufficiently large to keep the slot m entirely closed or covered when the plate B is moved to its fullest extentin either direction, as hereinafter described. The body A is designed to be secured to the ordinary spring of the truss by screws or rivets, which pass through the holes 15, or in any othersuitable manner. The screw-holes o o are sufficiently near together to enable theplate B and its pad J to be turned or revolved laterally without bringing the sides of the slot m into contact with the screws as.

In the use of my improvement, when it is desired to move or adjust thepad on the body A the screws m are turned out slightly, thereby releasing the hold of the. plates 0 O on said body and the hold of the nut Eand cover D on the plate B,after which the pad may be readily moved back and forth on the body, tipped vertically to any angle, or rotated laterally on the nut E to bring it into any desired position in a manner which will be readily obvious without a more explicit description. As the nut E is smaller than the chamber H, and the slot at considerably longer than the distance between the screwsxw, the pad may be moved vertically or at right angles to the body A to bring more or less of itabove or below said body, as the necessities of the case may require. The pad when the plate B is in the position with respect to the nut shown in Fig. 3 may also be moved laterally to a considerable distance either to the right or left without moving the clamping-plates longitudinally on the body A or uncovering the slot m. After the pad has been moved laterally, tipped vertically, rotated, or moved vertically at right angles to the body, as the case may be, to bring it into the desired position, as described, it may be readily secured 011 the body by simply turning in the screws 00 or, and thereby causing the plates GO to grasp the body A and the cover D, and nut E to grasp the plate B.

I do not confine myself to the use of the inner clamping-plate O, as a suitable rest or bed for the body A may be formed on the cover D, and one of the elaniping-plates dispensed with; or the inner elamping-plate C may be 5 formed integral with the cover D, if preferred. Neither do I confine myself to the use of the cover D, as one of the plates 0 C may be made of such size as to cover the slot on in the plate B and said cover omitted, although I deem it 10 preferable to use it.

Having thus explained my invention, what I claim is- 1. In a truss, the plate B, provided with JOSEPH F. NOONE Witnesses:
